When you build a sprinkler system, you need to make sure that you carefully choose your sprinkler pipes. The wrong pipe can leave your system vulnerable to damage. While PVC has been a standard for sprinkler pipes for many years, in most situations a polyethylene pipe will make a better choice.
An Analysis of PVC Pipe
Polyvinyl chloride, or PVC, sprinkler pipes are durable, but they do have some limitations. Because PVC is a rigid pipe, you will not be able to bend your pipe around corners, so you will end up using more connections than you would with another type of pipe. Also, you need to be careful when laying PVC in the bottom of a trench. If the bottom of the trench is not even, you can break your PVC pipe when you throw your fill dirt onto the pipe. Because of the need for a flat trench and myriad fittings, working with PVC can be time-consuming.
A second problem with PVC pipe is that it will not expand and contract with changes in temperature. If you have water left in your pipes at the end of your watering season, the water can freeze, and when it does, it can expand. This expansion can cause your pipes to break. You then have to track down the problem, dig out the pipe, and replace the damaged section of pipe.
An Analysis of Polyethylene Pipe
Polyethylene pipes come in flexible rolls, and instead of opening up a trench, you can lay pipe with nothing more than someone to buck the pipe and someone to drive the pipe puller. Eliminating the need to dig and fill a trench will save you a lot of time on your job site. Because polyethylene pipe is flexible, you can bend it around corners and reduce the number of fittings you need to do your job. Furthermore, when you have to make connections, you can use pinch clamps and insert fittings, which are much easier and quicker to work with than the glue or threaded fittings that you have to work with when you choose PVC pipe. Also, because polyethylene pipe is flexible, it will expand and contract with changes in temperature, so you don't have to worry about your pipe breaking when water freezes in the pipe.
While PVC is not a bad choice for a sprinkler system, there are better choices on the market. By choosing polyethylene, you make the installation process quicker, and when you save time, you save money. You also have a pipe that should last longer without problems than a PVC pipe. Ergo, polyethylene pipe is the better choice.
